What were you trying to do that didn't work?
We attempted to turn on and off virtio-net (NetKVM) Ethernet adapters using `netsh` commands, but these operations took excessively long. Reproducible consistently on systems with NetKVM driver configured 4queues, rx_queuesize=1024, significantly exacerbated when Windows Driver Verifier is enabled, and "LazyAllocTimeMs" is displayed as -1. This issue disappeared when LazyAllocTimeMs was shown as an accurate value.

Please provide the package NVR for which bug is seen:

• CPU=AMD EPYC 7313 16-Core Processor
• virtio-win-prewhql-0.1-283
• kernel-5.14.0-590.el9.x86_64
• seabios-bin-1.16.3-4.el9.noarch
• edk2-ovmf-20241117-3.el9.noarch
• swtpm-0.8.0-2.el9_4.x86_64
• qemu-kvm-core-9.1.0-21.el9.x86_64

How reproducible:
100%

Steps to reproduce
1. Configure a Windows VM with virtio-net NICs using multiple and large queues (e.g., `NumOfQueues: 4`, `RxQueueSize: 1024`).
2. Enable Driver Verifier for our netkvm.
3. Boot the Windows guest OS.
4. Open an elevated command prompt.
5. Execute: `netsh interface set interface name="Ethernet" admin=ENABLED`
6. Execute: `netsh interface set interface name="Ethernet" admin=DISABLED`
7. Check the execution time of commands.

Expected results
Both turn-on and off `netsh` commands should complete promptly, typically within one second.

Actual results
Both turning operations on and off can take unacceptably long times.

Notes:
In the screenshot of attachment, the Disable operation often takes significantly longer. For the current NIC (`NumOfQueues: 4`, `RxQueueSize: 603`, `TxQueueSize: 256`, `LazyAllocTimeMs: -1):

• Disable took more than 2 mins.
